Corruption and bad links using exchange voices on score with parts
Go to measure 18. See the cue notes in Fl II and Oboe I? Those were added after parts were generated. They're small, they have slurs, they're in second or third voice, and the play option is unchecked. Now go to Oboe I or Fl II. Don't worry about the octave in Fl II, It's on piccolo first. There are missing notes, none of the notes are small, and they all have play checked, there are no slurs. They are all in first voice, full measure rests on top of phrases, so the score is corrupted, though I get no notification when I load the score.
I did NOT write anything in the parts here. I was writing to score only.
It also gets crashy once you start poking around the parts. Here's a pic, to hedge my bets:
